Ohhh Ohhh Ohhh Ohhh OOOOOO OOOOO oooooo

thats how a woman would,, er might react

ohhh this is the most beautiful spectra I have seen so far

CERAMICS ROCK,,, no no not ROX rock hehehehehhe

roxism not intended,,,

oooo ooo ooo
hehehehhe

more ooo ooo mmm yummm

Now put that thru da fishey Babel lator.....

ok ok without much to do,,, into the pjism without delay,,,,,,,


gottttttaaaa seeeeee mmmmmm how it is,,,, oh dam need to jury rigism a precondensim toism with it,,,,,, time time time

gawd have I been sniffing mercury again,,, feel like a mad hatter from alice in wunderland... hehehehe

ok here is brand new less than 1.5 hrs old,,, and the current spectral emission of it

it is so balanced its not funny

no surprise they are so highly rated...

and best of all the halides cant destroy the lamp as per the normal,,, I hav now found the true lamp to overdirve by a percentage,,,

it can take double the temp, and not self destruct........

you are late elken

I have been overdriving this lamp at 250W since some months

now, no joking, you say it can handle more temperature than HQI, this is by nature of the materials?

ahhhhh so you hold secrets, then,,, hmmmmmmmmmm

just a few ones

out with it,,,,,,

spill the beans,,,,, out with it.

as a matter of fact Roxie,, sweetie etc etc etc,,

you hold too many secrets,,,

you have a purpose,,,, now it is time to come out with the agenda,, ehehehheheh,,

well, here is some advance;

CMD 150W striped burning capsule inside an eliptical reflector overdriven at 250W.

small and slow steps, I don´t like runing.

ahhhhhh I agree,, perfection rather than destruction,,

thats why I have shown my dislike at runaway tests without knowledge first,, serves no purpose except to mislead and misinform...

My personal belief is not to go up in power but to reduce power and double brightness,, this is the true path to the holy grail

another step I wish to do is exactly that,, make a custom reflector to suit apparent field required to satisfy at least a 450mm light cone..

I also feel that these CDM lamps are more superior to the current UHP quartz lamps

Ok now in PJ

oh my F^%$^$^ gawd,,, this lamp beats the living devil out of the HQI by 2 city miles and ten country miles,,,,, it is stupendious

The colour RGB mixing is almost nye perfect,,,, colours not visible before are now there, in all thier glory

yea, I agree with you that "brute force" 1000W lamps so we have a brighter picture is not the way to go... (well, not the way I would go) efficiency improve is the way going... 250W at lamp sounds rasonable for me for a 500 lumens DIY.

ohhh my there is no turning back,,,,, the COLOUR THE COLOUR,, and yes I am shouting,,,,,


just being watching TV on it,,, gawd,,, the reds the blues

th CRIMSONS,,, mmmmmmmmm

yeah yeha I am getting very carried away here,, but you have no idea of the truth,,,,,,,,,,,,,

and now for the real truth,,, hehehhehe I fibbed

I am running a 150watt,, no reflector,, 330mm /330mm fresnels std trippy

and it equals the 400 watter in brightness,,, but beat the hellout of it in every other way , without doubt,,,,,,

if others dont believe,,,,, heheh not my problem,,,, I have been researching and playing and more playing for over two years now,, and have learned more crap than I wished too,, but now feel that I win,, and have reduced the running cost by 60%... and a better picture..

oh and this was very very crude I took thatpreconden from yesterday and hand held it against lamp,l and it filled the entire screen with hmmmm dare i say it double the brighteness,,, ( sorry rox another figure pulled from air again ),,, now is nearly time to get a meter,,, the Luxie kind,, because now I feel real info is at hand...

Ohhh sorry I am going on here,,,,,, BUT

another gain is temps are down so far, I gonna remove the heat shield and gain another 10% at least in light again,,,, this ceramic lamp outputs NO U/V at all, i have tested it

dammm why did it take me soooooooo long to do this......

oh temps used to run at 38 degrees,, now down to 21 degrees,, light engine shaded was at 49 degrees. now at 25 degrees

ok,, another interesting stat,,,,,

the contrast has gone thru the roof.....

Are you using your OGS400-109 ballast with the Philips Elken or did you get a 250 watter?

nup its a 100 volt 1.82 amp std ballast

and thats my anal of it,,,,,

Durako's view of my world

Rox what lamp are you playing with? Is it the single ender or a double?

DJ

Same to you pal!!! :angry:

heres lampism, shutdown beforeism goism inism PJism

ok here are some shots taken thru a polariser,, as old method with big arc taking direct shots no longer works, cam over exposes with small tight arc,,

you can see the arc stream between electrodesquite clearly..

Click to view attachment

So there's an arc inside a ceramic chamber and it's like - what - 1.5 cm long or so?

What's the lumens/watt rating on these puppies?

How do they compare watt for watt with heat output versus MH?

ok now time for pics

these are untouched snapped purely on pause with full auto cam settings

and to remind this is a 150watt lamp with std lens and dual 330mm's

live tv with two lights on in background

thats the philips CDM-TD 150W /942 RX7S ?

the arc is 10mm

mikyd1954 yes thats the one...

I have played with this one as elken (double ended) and also the G12 single ended ones Daz. I believe the burning capsules are identical on them.

you are right they are exact

Initially I was going for the G12 one... but the wiring was creating a shadow (there is a wire paralell to the ceramic burner on the G12) I tried hard solving that issue... no way. I finally decided striping the lamp. Now there is no wire, I am wiring the "lamp" from the back and front...

cam's battery charging, pics later.

Ok Daz here is the crunchie,,, our favourite ref pic,,


now for all out there this is a 150 watt lamp Ceramic
using a std trippy,,,,dual 330mm fressies,, nil reflector,, vertical config,,,nil precon,,, to be added later

oh and for further ref,, that is a wega 80cm tv bottom right corner running too,,,,

DAZ can you add your pic under mine please, for direct reference...


edit by dazzzla: it's done

elken: is this the benq lcd?
hey Dazz, loan elken your lightmeter for a few days
Rox: you think you can get 500 lumens from this bulb overdriven to 250?
give up some secrets man!

no my Benq went to lappie heavens months ago,,, the is the diamond view dv177,,, Mitsubishu

is essence what this lamp has proven for me is everything i have been premoting about emission lines matching LCD panel and how all of these things coming together to provide better colour rendering (nothing to do with CRI, CF filter rendering/mixing ) and vastly improved contrast as a result too..... and brighter picture too with much lower lumens,,, oh PS this lamp has a total of 14,000 lumens,,,,

now Iwill leave it to you out there to figure that one out

I will saythat I got this lamp today,, purely as an experiment,,

but not expecting any great results,, however I am blown away with what it has done for me,,,

I now can say that this is the lamp I shall base any further tests and setups on,,, I refuseto go to a higher wattage,, as it is economy I am looking for,, balanced out of course with decent projection...

also these lamps are $90 aud dollars cheaper than the HQI 400 w/d too,, so ergo,,,win win,,

edit,,,
i feel add a pro reflector plus precon and a pro lens,,,, it is a total winner, without doubt
there are no halides attacking the vessel as the ceramic is inert to them plus lower running temps, mean removal of heat shield ergo more lumies thru,, plus the lamp is so small that a tight light engine is easy to achieve..

I believe all of these single ended lamps are very much similar, never looked into the DE versions.

Philips Mastercolor CDM150/T6/942
Philips Mastercolor CDM150/SA/942 (short arc version, about 6mm)
GE CMH150/T/U/942/G12
GE CMH150/SA/G12 (short arc version, really hard to find)
Osram MC150T6/U/G12/940
Ushio USI-S150DM/A/UVP

here is the box,,, heheheh cant pic the real lamp,, cause my son is watching fith element on PJ,, hmmm

but pic is full scale of lamp,,, that is the old short ushio lamp next to it and of course that socially unacceptable habit calling smoking, pak of 30's smokes too

mmm, sorry friends, news will come later. take it easy with me

yes, everithing points on that direction mikyd. I have messured amazing results with that setup. The key is the improved efficiency on the eliptical and some key points...

ahhhhhhh ROXie you should kept shhhhhh,,, heheheheheh,, now I know

the truth is always out there,,,,


Damn my son refuses to let me have lamp he wants to finish watching fifth element,,,, hmmmmm

I wann measure for preconden,, azizs more light !!!! and I wanna rip out shield of heat,,,, oh well morrow is another day for play,,,,, but wait hey,,, it is day already another,,, hmmmmfff

awe... come on guys... put some numbers to these observations you're making... !! (where's the "pretty please" smilie ?)

One major reason I can see as far as an improvement is the fact that those 150W lamp are using a 10mm arc length... compare that to a venture PS 150W DE lamp (14,000k lumens too), but it is in a 19.0mm arc. Small arcs will lead to use of parabolic reflectors... another big '+' ... but 500 lumens ?! yikes ! Rox, what size LCD are you currently using ?

nice find guys.

cheers,
gs

Hey gadget,, I kid you not,,, this is a major step thru,,,

I have jsutdone a vid pic on cam,, but it is 5 meg,, wish i could upload it,, cause vid really shows what is what,,, hmmmmmmmmmm

basically I cant believe I have come down from 400 watts to 150 watts and ended up equal,, there is more to than just a small 10mm arc,,,, the spectral anal.....ysis is also a big part too,, the real usable lumens on matched lines for CF on LCD



for gadg

wow, if I knew that reaction I would have shut my mounth a bit longer...

This setup I am playing with is based on a 8" hamy Gadget. mmm it is a 150W yes but run at 250W gear. The 500 number I gave was reference but I bet it is brightner than 300 lumens for sure.

Please calm

(now I understand when it was me asking that many questions to others... and they were like stressed after the first 28 questions , damn I can´t with 3 )

We understand your excitement in all this elken, but for the most part most if not all of us here would still be very interested in lux numbers at your screen. I beg of you to satisfy our curiosity.
pleeeeeezzzzzzzzzzzzzzzz!!

I wish I could comply,,, need to get one now,, as there is real reason for it,,,,,,

think of it 400 down to 150,,,,, with bare bones, and a 330, conden fressie,, i need to get 220 fressie now but not std small on a big one....

square law here at play,,, and yet still damn good
